Application m an rn v, 1924, Serial mi. 704,650.

The invention relates to improvementsin storage batteries, and the object of the 1mwhich, when attached to the cells of an ordinary storage battery, will not orly' show at a glance the condition of the battery, as to being fully charged or otherwise, but will also length of tubeand size, will necessarily have to conform to that particular battery cell 1 show at a glance whether or not the plates of the battery arecovered' (hereinafter calledwater line) sufiiciently with the-solution contained in the cells.

The formof theinvention is illustratedin the accompanying drawing; Figure 1 showing glass tube (1) attached to wall of cell in battery (6); with attachments (2),

(3), (ft), and (5). No. 2 is iflange of tube,

No. 3 is lead gasket on inside of cell, No. 4; is

not, N o. 5 is threads on end of tube, No. 7 is float. I 4

There are numerous manufacturers of storage batteries and all vary in size, so, the

on which the device is to be installed.

The manner in which the device is in-.

stalled is done by boring two-holes, the size of glass tube in the cell of the battery at the storage battery, with elongated slots cut in.

Figure 2 shows front View of ordinary box, which Wlll allow tube and'float to be seen at a glance, and waterline at top. No.

i V ,No. 8 caps on ordinary storage batter provement, is; a visible built in hydrometer 1 glass tube No. 7 float No, 9 elongated slots Figure 3 shows glass tube'placed atbottom of cell. and'cell attachments, No; 1. tube, No.

3 gasket, No. 4: nut,"and No. 10 small "obstru'ction or lug built intube which will keep fioat 7' Figures 1 and 2 entering cell when fully discharged.

v The device herein described, which I'will pallstorage battery self tester, shows, the possibilities of attachments to knocked down? batteries, but if manufacturer. is inipressed with the herein described device,'-the glass tube "may be built in the cell 'at timeiof the manufacture, ina' manner'suitable to individual requireinents-moldod or attached as described. Glass tube to be made of suit- "able'stlength to withstand freezing tempera-j turesj. A gauge or suitablelrnarkings placed on'side or elongated slots on battery box will -show'the conditionof eachcell.

I claim-- I y Thelconibination with aconventional battery receptacle having opaquewalls adapted to'contain a battery solution, said receptacle having a pair of spaced (openings in one of said walls, an attachment detachably secured to said receptacle, said attachment having a vertical transparent portion disposed exteriorly of and entirely independent of one wall of the receptacle, said verticallytransparent portion neareach end thereof being turned inwardly and adapted to enter the spaced openings in the "wall, securing nuts for uniting said inturned en'dsfto'the battery wall, the-ends of said-vertical transparent portion being open to permit the entrance of the battery solution into said transparent portion to indicate the level thereof,

and a hydrometer mounted in said verticaltransparent attachment for designating the. I

strength of the battery-solution.
